CPU Statistics Test

This test auto-discovers the stack units of the Dell EMC S-Series switch, and monitors the current CPU utilization of each stack unit. If the stack unit is found to consume CPU resources excessively, then, this test will help administrators to determine when exactly did the CPU utilization peak - during the last 5 sec? or 1 minute? or 5 minutes? This revelation helps administrators troubleshoot the CPU spikes better.

Target of the test : A Dell S-Series Switch

Agent deploying the test : An external Agent

Outputs of the test : One set of results for each stack unit:CPU core combination in the Dell EMC S-Series Switch to be monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the host for which this test is to be configured.

SSH Username and SSH Password

Specify the credentials of a user who has the right to execute CLI (command-line interface) commands on the target switch and pull out metrics via SSH.

Confirm Password

Confirm the SSH Password by retyping it here.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

CPU usage in last 5sec

Indicates the percentage of CPU utilization of this stack unit during last 5 seconds.

Percent

By comparing the values of these measures, you can quickly figure out when exactly was the CPU usage maximum. Using this analysis, administrators can further investigate the real reason behind the sudden spike in the CPU usage.

 

 

CPU usage in last 1min

Indicates the percentage of CPU utilization of this stack unit during last 1 minute.

Percent

CPU usage in last 5min

Indicates the percentage of CPU utilization of this stack unit during last 5 minutes.
